Out of curiousity I experimented with building the smallest possible
static [x86-64][] [Linux][] binaries in several programming languages.
Each binary does the following:
1. Print `hi!` and a newline to [standard output][stdout].
2. Return an exit code of `0`.
I tested [Assembly][], [C][], [Go][go], and [Rust][rust] with various
optimization and build option combinations.
Here's a plot of the results (**note:** [log scale][] X axis):

Here's a plot of the smallest static binary sizes (<1k, linear scale X
axis):

Full Disclosure: `asm-opt` is the smallest *legitimate* result;
`asm-elf` uses dirty tricks from [Tiny ELF Files: Revisited in
2021][tiny-elf].
Source code, build instructions, a [CSV][] of results, and additional
details are available in the [companion GitHub repository][repo].
**Update (2022-01-01):** See [Tiny Binaries: Assembly
Optimization][tb-asm] for an explanation of the assembly results.
**Update (2022-02-24):** [Rust 1.59.0][] was released today
and makes it [significantly easier to create stripped
binaries][rust-strip].
**Update (2022-03-02):** Added a [follow up post][tb-redux] with Go
1.18rc1, Rust 1.59, and TinyGo 0.22.
